lApplioation filed September 5, 1899. serial No. 729,573. (No model.)

To all whom it may concern:

Be it known that LGEORGE Woon RAMAGE, a citizen of the United States, residing at Ohicago, inthe county of Cook and State of Illinois, have invented a new and useful Globe Ohronometer or Clock, of which the following is a specification.

My invention relates to improvements in globe chronometers or clocks in which horizontally revolving circular dials, pointers, and a circular crystal with rims attached, in conjunction with an ordinary terrestrial globe or circular case, either stationary or revolving, (but for purpose of illustration is made stationary,) and clockwork, are made to show the time at all points of the world at the same moment with the relation of the time at any one point to that of all other points, the mean solar and standard times where standard time is used, on which part of the earth itis night and on which part day time, at w hat particular moment during the twenty-four hours it is the same day of the week and the same date of the month in all parts of the earth, where the legal day and date of the world as adopted by civilized nations begin and end and what part of the world is a day and date ahead of the balance, gives the geography as well as the time of the world, causes the bee holder to naturally read time correctly, and in addition to its special features can be used for any purpose for which the ordinary clock is employed. I attain theseobjects by the mechanism illustrated in the accompanying two sheets of drawings, in which Figure l is in part an elevation and in part a vertical section of the chronometer or clock, showing the various parts as regards their relation to each other. Fig. 2 is an elevation of a section of a globe A, crystal F, rims D and E, and dials B and O at the meridian of one hundred and eighty degrees of longitude east and west from Greenwich at the hour of twelve midnight. Fig. 3 is an elevation of a section similar to Fig. 2 at the meridian of Greenwich at the hour of twelve noon. Fig. 4:

is a vertical section of a portion of structural and working parts through center of globe.

Similar letters refer to similar parts throu ghout the several views.

. The globe A, with strengthening-disks M M and K K, together with crystal F and rims D and E, base N, and pedestal O, constitute the framework of the chronometer or clock.

A represents a hollow globe made of two hemispherical sections divided at the equator by a transparent annular band or crystal F, with rims D and E, to which the hemispheres are properly fitted and secured, as hereinafter described.

B represents an annular dial, which is made to make one revolution every hour, the face of which is divided into equal spaces numbered from 1 to 60, the number of minutes in an hour, and these spaces are subdivided into fractions of a minute, and is termed a minute-dial. This dial is intended for use only at the point or within the hour-belt of standard time where chronometeror clock is used, reference being had to divisions on hour-dial O for minutes at all "other points.

0 represents an annular dial, similar to the minute-dial B with the exception of havinga deeper or broader face, which is made to make one revolution every twenty-fourhou rs, the face of which is divided into twenty-four equal spaces in two sections properly numbered, one section representing the hours from one a. m. to twelve noon and the other the hours from one p. m. to twelve midnight, constituting the twenty-f0 ur hours of the day, these spaces being subdivided into fractions of an hour, the hours of twelve noon and twelve midnight having designating-marks in addition to numerals, as hereinafter explained, and this is termed an hour-dial.

D represents the upper rim of crystal F, on which is placed the degrees of longitude from 0, orthe meridian of Greenwich, east and west to 180, properly marked and numbered, the hour-belts of standard time, designated by different colors and names, such as Eastern time, and names of towns or cities opposite their respective degrees of longitude,

or other suitable matter.

E represents the lower rim of crystal F, on which is placed the degrees of longitude, properly marked and numbered, similar to and corresponding with those on rim'D, or other matter, as may be desired.

F represents a crystal which is set into and securely attached to rims D and E and may be made of any transparent substance having sufficient strength to sustain the weight of upper hemisphere of globe A.

G G represent push-buttons which operate spring-fastener II.

H represents a spring-fastener operating in connection with catch Ct, one being placed on the inner surface of either side of globe A.

I represents a metal strap, four or more in number being placed equal distances apart around circumference of globe and securely fastened to inner side of rim Eand to disk K.

J J represent metal bands placed around outer surface and securely fastened to upper and lower hemispheres of globe A and making a partthereof.

K K represent disks fitted closely to inner surface of upper and lower hemispheres of globe A.

L L represent supports firmly secured to inner walls of hemispheres, to which disks K K are fastened.

M M represent disks made convex on one side, so as to fit inner surface of upper and lower ends of globe A, to which they are securely fastened.

N represents a base, which may be of any design or made of any suitable material.

0 represents the pedestal, which is made hollow for the reception of bolt P. It is securely fastened to globe A and fitted into a socket in base N in such a manner as to allow of its turning therein.

P represents a hollow or tubular bolt so made as to enable a wire to be passed through it in case it is desired to operate the mechanism within the globe by electricity. It is firmly attached to the base N and having a thread at its upper end is screwed through a nut b, which is fastened to disk M.

Q represents a solid bolt attached to disk M at top of inner surface of globe and projecting through globe, with a thread cut on its outer end to receive thumb-screw R.

R represents a thumb-screw fitted 011 bolt Q, so as to screw down tight on globe A.

S S represent pointers or hands of different colors, curved so as to fit circumference of globe A and marked, respectively, Standard and Solar or otherwise, which are [itted at their upper ends over bolt Q, and held in a stationary position by thumb-screw R. Their use is to point to the degree of 1ongitude of the place at which ehronometer or clock is used, one being made to point to the degree indicating or marking mean solar time and the other to the degree marking standard time or any other points, as may be desired.

T represents clockwork which operates dials 13 and C, any suitable clockwork answering the purpose, that shown in accompanying drawings forming no part of my present invention.

U represents a tube placed perpendicularly directly over the winding-post of clockwork, through which key is passed for winding p u rposes, and V represents a keyhole.

Figs. 2 and 2 are sections of elevations, in which A A represent sections of globe; l) and E, upper and lower rims; F, crystal, and B and G dials, Fig. 2 representing section at one hundred and eighty degrees of longitude east and west from Greenwich at the hour of twelve midnight, which hour is marked by a black disk, besides numerals XII. Fig. 3 represents section at the meridian of Greenwich at the hour of twelve noon, or at the same moment of time as represented in Fig. 2, at which moment it is the same day of the week and date of the month at all points of the earth. As soon as the hours of twelve have passed these points a new day and date has begun at 180 after which time that part of the earth where the new day and date is in vogue includes the territory of the earths surface included in the degrees of longitude east from the black disk at 180 to that at the hour of twelve midnight, and the time in all territory in opposite direction from 180 is a day and date behind. Thus at all places on the earths surface to the left from 180 to the hour of twelve midnight it would be, say, Saturday, August the 525th, and at all places to the right from the 180 to the hour of twelve midnight it would be Friday, August the 21th, which, lessening as the earth turns on its axis, would end when the hour of twelve midnight marked on hour-dial C again stood opposite the 180 marked on rim D and a new day and date-Sunday, August the 26thwould begin. A. line may be placed on the map covering globe A to indicate the irregular course representing the one hundred and eighty degrees of longitude, as provided by international agreement, for the purpose of marking time correctly.

Fig. 1- shows a vertical section of one-half or all that is necessary hO show to illustrate working parts and mode of construction. AA represent sections of a globe. B represents a minute-dial, and C an hour-dial, d cl indicating slots cut therein for the purpose of mov ing regulator and to allow key to pass through for winding clockwork T, these dials being so adjusted to clockwork to allow of their being moved forward or backward by hand by turning minute-dial B in similar manner as that used in setting the hands of an ordinary clock forward or backward Without injury to the mechanism. D represents the upper and E the lower rims of crystal, and F the crystal, fitted closely into rims D and E and securely fastened therein. G represents a push-button, and H a spring securely attached to disk K at one end and at the other fitted snugly into a slot and over the under side of catch Ct, which is firmly attached to inner side of rim D. I represents a metallic strap firmly attached at one end to inner side of rim E and at the other secured to disk K, the rims D and E, crystal F, spring and catch H a, which is operated by push-button G, together with strap 1, forming the connection between the upper and lower hemispheres of globe A, the

IIO

crystal F also protecting and lighting the faces of dials B and O. J J represent metallic bands which are placed around and flush with the outer surface of the upper and lower hemispheres of globe A and firmly attached thereto for the purpose of adding strength thereto and being made to project beyond the rims of hemispheres provide secure sustainers for crystal-rims D and E. K K represent disks of wood or other suitable material made in a true circle and fitted closely to inner surface or wall of globe A, acting as braces for holding hemispheres in true position and as supports or foundations for structural and operating parts. L L represent supports firmly attached to inner surface or wall of globe A, to which disks K K are securely fastened. T represents a clockinovement which operates dials B and O, the gearing for the hour-dial being so constructed as to make one revolution every twenty-four hours, while that for the minute-dial revolves once every hour.

The hour-numerals always showing in advance of those of minutes belonging to succeeding hour causes the observer to naturally read the time properly as ten hours and twenty minutes (ten twenty) instead of the usual twenty minutes past ten.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A geographical globe bisected on the equator and having its sections arranged with an interval between them, in combination with a transparent annular band occupying the said interval, fastening devices which hold the said band to the said sections and rotary time-indicating devices arranged within the same, substantially as set forth.

2. A geographical globe bisected on the equator and having its sections arranged with an interval between them, in combination with a transparent annular band occupying the said interval, fastening devices for holding the said band to the said sections, rotary time-indicating devices arranged within the said band, and means of support which hold the said globe stationary with respect to said devices, substantially as set forth.

3. In combination with two juxtaposed annular dials having different systems of graduation marked thereon and mechanism for in dependently rotating them, an inclosing rela= tively stationary geographical globe which is bisected and permits the said rings to be inspected through the annular interval between its parts, a transparent band occupying the said interval and two pointers on the exterior of the said globe and applied to the said rings respectively, substantially as set forth.

4. In combination with inclosed time keeping mechanism, a globe divided into two sections, a transparent band occupying the interval between the said sections, spring-fas teners for holding the upper section to the said band and push-buttons protruding through the said globe to facilitate the release of the said fasteners, substantially as set forth.
